Specification of Letters Patent.

Application led December 24, 1909.

Serial No. 534,775.

To all whom it may concern.'

Be it known that I, GEORGE Focrrr, a citizen of the United States,residing at Hoboken, in the county of Hudson and State of New Jersey,have invented a new and useful Bottom-Door Dump-Bucket, of which thefollowing is a specication.

This invention has relation to bottom door dumps and it consists in thenovel construction and arrangement of its parts hereinafter shown anddescribed.

The object of the invention is to provide a simple and durable bucketespecially adapted to be used for holding and depositing mixed concreteand similar material and its configuration and arrangement of parts issuch as to facilitate the egress oi the material from the bucket duringthe act of dumping.

With the above object in view the bucket includes a body having at thelower portions of its front and rear sides converging seetions theconverging` section at the front side being longer than the convergingsection at the rear side. A bottom or door is hingedly attached to theconverging section oi' the rear side of the bucket and is provided onits side edges with flanges adapted to overlap the lower portions of thesides of the bucket body. A stirrup is applied to the said door and theends of the stirrup are adapted to extend up along the sides of the bodywhen the door is in closed position. The ends of the stirrup areprovided with elongated slots. Levers are fulcrumed to the sides of thebucket and are provided lat their working ends with elongated slots.Links are pivotally and slidably connected at their ends with both thelevers and the ends of the stirrup and serve as means for drawing andholding the bottom in closed position when the levers are swung down. Ayoke is operatively connected with the said levers for automaticallyswinging the same to open the door when the bucket is lowered to theground.

In the accompanying drawings ;-Figure 1 is a front elevation of abucket. Fig. 2 is a side elevation of the same. Fig. 3 is a transversesectional view of the same cut on. the line 3-3 of Fig. 2. Fig. 4 is atransverse sectional view of the same eut on the line 4,-4 of Fig. 1.

The bucket includes a body 1 having a the lower portion of its frontside an inclined section 2 and at the lower portion o1 its rear side aninclined section 3. The said sections 2 and 3 converge toward each otherat their lower edges and the section 2 is longer than the section 3. Adoor 1 is hingedly attached at its rear edge to the inclined section 3and is provided at its side edges with upstanding flanges 5 adapted tooverlap the sides of the body 1 when the said door is in closed ositionagainst the lower edges of the said body 1. A strengthening band 6 isapplied to the outer surfaces of the lower edge port-ions of the body 1.Angular pedestals 7 are attached to the door 4t and are o1 suchconfiguration as to hold the body 1 in an erect position upon levelground or a level support when the door is closed and while the saidbody is being filled with material. Z braces 8 are interposed betweenthe intermediate points of the pedestal 7 and the door L1- and areadapted to brace both the door and the pedestals against the strain towhich those structures are subjected. A stirrup 9 is applied to theintermediate portion of the door 4 and the end portions of the saidstirrup are adapted to project up along the sides of the body 1 when thesaid door is in closed position. The end portions oi the stirrup 9 areprovided with elongated slots 10 which are approximately in alineinentwith the hinge pivot point oi the door l-. Levers 11 are fulcrumed tothe sides oi the body 1 at points 12 and the said points l2 are nearerthe vertical plane of the upper section of the front side o1 the body 1than the forward end of the slot 10.

The levers 11 are in the form of bell cranks and are provided at theirworking ends with angular-ly disposed extremities 13 having elongatedslots 14. rlhe extremities 17 are approximately parallel with the collarend portion of the levers 11. Links 15 are provided at their upper endswith pins 16 which pass through the slots 14 of the extremities 13 thusestablishing both pivot and sliding connection with the levers 11. Thesaid links 15 are provided at their lower ends with pins 17 which passthrough the slot 10 in the ends of the stirrup 9 and thus both pivot andsliding connection is established between said links and the saidstirrup. The opposite end portions of the links 15 are angular-lydisposed toward each other, the apices of the angles occurring adjacentthe pivot point 12.

The power end portions of the levers 11 Patented Feb. 28, 1911.

are of such a length that the forward ends of the levers may move in anarc which terminates at one. end at a point between the upper and loweredges of the inclined section 2 and at its upper end at a point belowthe upper edge of the front of the body 1. A cross rod 1S connects theforward ends of the levers together and the said rod located in front ofthe front side of the said body 1. A yoke 19 is pivotally connected atits ends with the rod 18 and said yoke is adapted to hang pendent on thesaid rod and when the door et is in closed position against the body 1and the forward portions of the lever 11 are swung down, theintermediate portion of the yoke 19 will be below the level of the lowerportions of the pedestals 7. By this arrangement and assemblage of partsit will be seen that when the door is closed against the lower edges ofthe sides of the body 1, the pins 17 carried at the lower end of thelinks 15 will be at the forward end of the slots 10 and the pins 1Gcarried at the upper ends of the said links will be at the forward lowerend of the slots 111 in the extremities 13 of the levers 11, also thepins 16 will be slightly in advance of a straight line passing throughthe centers of the pins 17 and the pivots 12. The forward ends of thelevers 11 will be swung down and rods 18 will be against the outersurface of the inclined section 2 of the front of the body 1. Thus itwill be seen that the door l is held in locked position against thelower edges of the body. lVhen the parts are thus locked together andthe bucket is lowered to the ground for the purpose of filling, the yoke19 is swung upwardly and may be permitted to rest upon the surface ofthe ground. After the bucket has been illed with material it is elevatedand conveyed to any desired point when it is lowered and as the bucketapproaches the ground or other foundation the intermediate portion ofthe yoke 19 is the first to engage or come in contact therewith and thesaid yoke will swing the forward end of the levers 11 upward. As thesaid levers 11 turn upon the pivots 12 the extremities 13 are movedtoward the rear side of the body 1 and consequently the pins 16 arecarried behind the line from the centers of the pins 17 to the pivotpoints 12 and the levers 11 continue to swing until the cross rod comesin contact with the upper vertical portion of the front of the body 1.At

the saine time the pins 16 move along the slots 11 as the rear ends ofthe said slots are inclined downwardly and thus it is possible for thedoor a to swing upon its hinge connection with the section 3 of thebody 1. As the said door begins to swing to an open position, the pins17 move along the slots 10 until they come in contact with the rear endthereof and complete the opening movement of the door 4. After theinitial opening movement of the door L1 the material within the body 1upon the relatively long inclined section 2 bears directly against theinner face of the door, by gravity, and thus the said door is subjectedto a thrust strain approximately at a right angle to its plane. Thisthrust strain forces the door open promptly,` and when the forwardportion of the bucket has become emptied of its contained material, thematerial at the rear portion of the bucket descends along the inclinedsection 3 and sweeps across the inner face of the door l and clears thesame.

Having described the invention what I claim as new and desire to secureby Letters Patent is l. A bucket comprising a body, a door hinged to thebody, a lever fulcrumed upon the body, and a link slidably and pivotallyconnected with both the lever and the door.

2. A bucket comprising a body, a door hinged to the body, a stirrupattached to the door and having slotted end portions projecting abovethe upper surface of the door, a lever fulcrumed to the body and havinga slot in its working end, a link having at its ends pins which slidablyand pivotally engage the slots of the stirrup and lever, respectively.

3. A bucket comprising a body, a door hinged to the body, a stirruplying under the intermediate portion of the door and having end portionsprovided with slots,

levers fulcrumed to the sides of the body I and having slots in itsworking ends, and links having pins at their opposite ends which engagethe slots of the stirrup and levers, respectively.

In testimony that I claim the foregoing as my own, l have hereto affixedmy signature in the presence of two witnesses.
